A Pie Chart is a useful visualization technique to display quantitative information for different
categories that also have a meaning as a whole.
As with all other series, the Pie Series must be appended in the <em>series</em> Chart array configuration. See the Chart
documentation for more information. A typical configuration object for the pie series could be:</p>

<p>In this configuration we set <code>pie</code> as the type for the series, set an object with specific style properties for highlighting options
(triggered when hovering elements). We also set true to <code>showInLegend</code> so all the pie slices can be represented by a legend item.
We set <code>data1</code> as the value of the field to determine the angle span for each pie slice. We also set a label configuration object
where we set the field name of the store field to be renderer as text for the label. The labels will also be displayed rotated.
We set <code>contrast</code> to <code>true</code> to flip the color of the label if it is to similar to the background color. Finally, we set the font family
and size through the <code>font</code> parameter.</p>

<p>This option is useful during Component construction to add DOM event listeners to elements of <a href="Ext.Component.html" rel="Ext.Component" class="docClass">Components</a> which
will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
<pre><code>new Ext.panel.Panel({
    title: 'The title',
    listeners: {
        click: this.handlePanelClick,
        element: 'body'
    }
});

<p></div></li>
</ul><br></p>

<p>
<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple events. For example:
<pre><code>myGridPanel.on({
    cellClick: this.onCellClick,
    mouseover: this.onMouseOver,
    mouseout: this.onMouseOut,
    scope: this // Important. Ensure "this" is correct during handler execution
